As a gag, the character might be literally shocked as a result.

Not to be confused with LightningGlare or BeamOfEnlightenment. Or DramaticThunder, which is... [[ExactlyWhatItSaysOnTheTin dramatic. And thunder.]] For a more direct metaphor of the effects of being struck by ''actual'' lightning (or other electric surges), see XRaySparks.

Note that in French, this is an expression ("coup de foudre") meaning LoveAtFirstSight.

Also not to be confused with [[Franchise/{{Pokemon}} Pikachu]]'s signature attack. ----!!Examples:

[[AC:{{Anime}} and {{Manga}}]]* Many times in ''Manga/LuckyStar''.* Sakaki from ''Manga/AzumangaDaioh'', overwhelmed by the cuteness of a photo of kittens.** Same series, when Kaorin and Chihiro discover that Chiyo not only ''makes her own lunch'', but is actually quite good at it.* Happened to Misaki in ''Manga/KaichouwaMaidsama'', when Hinata chooses "Misa-chan" in a photo op prize should he win the Sweets eating event in the Maid Latte.* This happened to Setsuna in ''Anime/NegimaSecondSeason'' when she made a particularly [[CannotTellAJoke bad word-play joke]] (uncharacteristic of her in that she [[TheComicallySerious made a joke at all]]). She apologized for it after the lightning cleared.* Used often by the members of the ''Manga/OuranHighSchoolHostClub'', especially by the highly theatrical Idiot King, Tamaki.** Amusingly enough in the anime the resulting lightning bolt will actually hit Tamaki resulting in XRaySparks more often than not.* In the ''Anime/MagicalGirlLyricalNanohaStrikerS'' [[AllThereInTheManual supplementary manga]], privates [[ThoseTwoGuys Alto and Lucino]] gush over a cute, floating, child-like mage in a military uniform... shortly before said mage floats over to them and introduces herself as Sergeant Major Reinforce Zwei, their superior officer. Cue ThunderShock.* Used interchangeably with the BeamOfEnlightenment in ''Manga/RanmaOneHalf'', both for comedic and serious purposes, but mostly the former.* Scar, SerialKiller on a RoaringRampageOfRevenge in ''Manga/FullmetalAlchemist'', has [[CutenessProximity this reaction]] when he sees Xiao Mei, a [[PandaingtoTheAudience tiny panda.]]* ''Manga/{{Jin}}'' overuses it to the point of being {{narm}}tastic. Sometimes it feels like a third of a chapter are ThunderShock panels.* In ''Anime/DragonBall'', Goku's first transformation into the Great Ape is heralded by this.

[[AC:{{Light Novel}}s]]* ''LightNovel/ACertainMagicalIndex'': Index and Aisa (plus a ColorFailure), when Komoe starts [[{{squee}} happily]] talking about how Touma was a naughty boy, and how "various things" happened. Though in this case it's more like a Thunder ''Rage'': "[[HaremGenre Another one]]?" "That bastard."

[[AC:{{Visual Novel}}s]]* Shows up in a FreakOut in ''VisualNovel/PhoenixWrightAceAttorney''. [[spoiler:Damon Gant]]'s, to be specific.* Experienced by both Nagisa and her theatrical mother, Sanae, ''VisualNovel/{{Clannad}}''. In Nagisa's case, her antennae-hair is temporarily withered as a result.

[[AC:{{Webcomics}}]]* Exploited in ''TsunamiChannel'', with one comic having the characters intentionally saying shocking (untrue) things (i.e. "I'm pregnant!") in order to repeatedly electrocute another character.

[[AC:WesternAnimation]]* In ''WesternAnimation/StevenUniverse'', Greg experiences this when realizing Rose hasn't quite got a grasp on how seriously he wants to take their relationship.* In ''WesternAnimation/TheLegendOfKorra'', when Jinora asks Asami if [[LoveTriangle she knows that Korra has a crush on Mako]], Korra gets a ThunderShock in the background, as well as a very [[NightmareFace odd expression]] across her face, complete with WideEyesAndShrunkenIrises.* Expertly lampshaded in ''WesternAnimation/DextersLaboratory'' with both Mandark and his Sister Olga.* Happens often in ''WesternAnimation/TheFairlyOddParents'' with [[BabysitterFromHell Vicky.]]-->'''Timmy:''' [[LampshadeHanging Did anyone else notice the lightning?]]----
